David - (you can tell I am upset because I called you David) - I profess no "like" of calculus. It is merely a necessary evil. I would much rather tutor in more pleasant subjects like drinking beer, goofing off, taking pictures of strangers on the street, or even how to enjoy your weekend in Michigan. Unfortunately, not many parents are willing to hire me for those subjects. Therefore I must engage in the art of calculus. Let me know when my lawyer gets in touch with you.
I do not share the opinion that a love of photography makes up for that other thing (which is so bad I cannot speak its name), but I do appreciate the sense of humor exhibited by He Who Flies and Tutors.
